MaximumDeterminizedStates

Maximum number of automaton states required for the query. Default is 10000.

OpenSearch uses Apache Lucene internally to parse regular expressions. Lucene converts each regular expression to a finite automaton containing a number of determinized states.

You can use this parameter to prevent that conversion from unintentionally consuming too many resources. You may need to increase this limit to run complex regular expressions.

int?
